Drag audio clip over another clip, clip replays fast

Is this supposed to happen?

1. Insert audio clip on the music track

2. Insert another audio clip on the music track next to it

3. Drag second clip over first clip somewhat

4. Displayed length of second clip shortens by the amount of overlap

5. Second clip plays back at higher speed but original pitch

6. Second clip can only be fixed using "power tools" manually setting "modified audio length" back to original.

This explains some audio corruption I got on my recent project where that overlapping must have happened inadvertently. If you speed up the audio more than just a little using that method it quickly sounds pretty horrible.

Interesting. I've done that by accident with video clips and the second clip just replaced the first. What a pain to fix. __________________________________

Hi Peter,

2. Insert another audio clip on the music track next to it
When you say "next to it" do you mean in the next highest numbered music track? Or are you talking about 2 seperate audio beds that you are trying to overlap in the same music track?
I don't think you can "overlap" 2 seperate beds (e.g. Fade one out as the other fades in), in just one music track.
You'll need to use two audio tracks or PIPs to do that. If... that is what you meant.

I mean the second clip goes on the same track as the first clip and to the right of it. If you then move it left (as if to overlap it with the first clip, which indeed you can't actually do) that's when the odd behaviour I described arises. I'm not particularly wanting to overlap it - as you say, you'd need to have the two clips on two different tracks and create fade ins/outs yourself if you wanted a crossfade - it's more a matter of having encountered audio corruption in a real project, this is how it must have accidentally happened, and is it supposed to behave that way for some useful purpose?

Hi Peter,

Ok, now I understand.

I think it is matter of having 2 audio clips occupying the same physical space at the same time. The left clip occupies "it's" space, so when you slide the right clip to the left, it can not occupy the same space as the clip that is already there. So it's size is decreased by you sliding it into the wall of the existing left clip.
Then PD8, in perhaps a misguided form of assistance, automatically speeds this moved clip up, in order that the full content of the clip is retained in the new smaller piece of real estate that you have given it.

The Minute Waltz takes a minute to play. But by sliding and squashing it against the left clip (which creates a smaller space for it to occupy), it is like you are asking that Minute Waltz be played, but you’re only allotting a 45 second block for the whole piece to be preformed, so PD8speeds it up to get the whole Minute waltz preformed in 45 seconds.

Is that normal behavior? In PD, yes.
The only option is to trim the clips to make them fit in the allotted amount of space you are giving them in the audio timeline.
